This invention relates to loading blocks for preparing semi-cylindrical or half 'bear' ings for accuratepositioning in the dummice or shop forms onwhich theyare mount ed preparatory to finalmachining, and has for its object an improved organization of parts by means of which this operation may hearings be very accurately mounted upon the dummies both with reference to them, and, in the case of half bearings where two are mounted upon the dummy at once, with reference as well to the ring which holds them clamped about thedummy orspindle' engaging shaft. The apparatusherein disclosed makes possible both speed and ac- 1 curacy in these respects;

In the drawings: I Figure 1 1s a plan view of the baseor table with the outer or locating shell and the central stud. of the device showntin full circles, while such removable partsafas the i one another by dummy, the individual shell,a nd the bearingare shown in dotted lines. I 1

Figure 2 is an elevational view partly in section, with the removable parts indicated by dotted circles in Figurel similarly indicated in position in this view, which is taken along the line 2 2 of Figure 1.

A indicates a base or table, through which extend upwardly bolts or similar members B, which serve to anchor in position the outer shell. C of the loading device. This shell, it will. be observed, has two concentric and supporting top surface portions asD and. F, preferably. spaced somewhat from the cut-away or trough portion E. I

Also supported by the block concentrically with respect to the outer shell G is the stud or pillar G, which mayif desired be provided with flanges H, which rest uponthat portion of the table intermediate the body of the stud G and the 0f the bearing shells upon the heading split ring :L ;the middle line of the-split.ring, viewed horizontally, is. just mid-way between the higher surface F. p sembly has beenthus brought about, iteauses the. accurate positioning of I removed and wall or shell The external diameter of this stud is such .t-hahthe dummy K will just fit over it; the I dummy or adapter is of such a length that its, top edge lies appreciably about the top I .ofgthe stud G. When twohalf bearings as M and N are to be mounted upon the dummy theyare held about the projections Kf on the dummy by means of the separable, or split ring L.

and thickness of the several parts are so proportloned that when thelowenfianges M and Nare rested is rested upon the surface F,

top and bottom flanges P and Qrespective'ly which has first been placed in position over the stud G, the easiest procedure,,even for a .carelessoperator, is to allow the lower flanges Q, of thehalf bearings to rest upon thesurfacesD and to rest the split ring upon the When, however, the 'as the t-we matched between the ends of half bea n I m iay ,thetdummy K, The temporarily assembled structure, may .1 then be. easily and ,quickly tossed into thebin or container for a positioning 1 uponthe. machine spindle when desired. The operative parts of this latter and the degree of cut desired upon the bearing shell having been the determining factors regulating the height of the shell and of the loading device and the relativeheights of its supporting surfaces D and F, it is obvious that the individual units when thus assembled andplaeed in quantity in a storage bin or container can be relied upon to be accurately and uniformly positioned with regard to the dummy or spindle-engaging shell K. i I

It is to be understood that by the term half-bearings I mean to include herein I From an examination of Figujre 2:1t w1ll be observed that the height surfaces D,and when the of the bearings and also mid-way between thetop' and bottom ends of the dummy K;

j It is obvious that before the tightening .means ont-he split ringL is brought} into action to force the half bearings M and Ninto tight relations about the adapter or dummy iK,

' relatively to when the two halves are assembled about the dummy or adapter, do not quite touch, as indicated at R in Figure l.

While it will be apparent that the illustrated embodimentsot my invention herein disclosed are well calculated to adequately fulfill theobjects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

hat I claim is:

1. A loading device for bearings, comprising a supporting base, a central locating stud adaptedto be removably engaged by a shellsupporting dummy, and a concentrically disposed encircling shell having a plurality of supporting surfaces whereon one edge of the bearing and its temporary encircling and clamping ring may be respectively rested at desired elevations relatively to the middle lengthwise point of the dummy and of the bearing shells respecth-ely.

2. A loading device for bearings, comprising a central stud and a spacedly encircling wall member having supporting top surfaces of suitable proportional height, the central stud being adapted to temporarily support a spindle-engaging dummy and the supporting surfaces of said wall member and in turn being adapt-ed to support the lower edges of a bearing shell and of a shell-holding ring respectively at desired assembled elevations one another and to the spindleengagin dummy.

3. A loading device for half bearings-and their temporarily encircling and clamping rings and supporting dummies, comprising'a locating stud over which the dummy is adapted to be positioned, and a coaxially positioned surrounding element having concentrically positioned supporting platforms whereon the bearing shells and their temporary enclosing ring are adapted to be rested, the height of each platform relatively to the length o1 the dummy and of the bearing shell and to the thickness of the enclosing ring being such as to accurately locate the two latter in desired position relatively to the lengthwise extent of the dummy.

4. A loading device for half bearings and their temporary encircling rings and supporting dummies, comprising, a central locating stud about which the dummies are adapted to be positioned,-and supporting platforms of calculated diverse height rela-,

tively to the length of the dummy, the length of the bearingshell, and the thickness of the encircling ring respectively, upon which the bearing shell and the encirclingring are adapted to be rest-ed, thereby accurately posit-ioni'ng them relatively to the lengthwise extent of thedummy. r 5*. Means for locating bearing shells in accurate position on a spind'le-enga ging adapter, comprising a central locating stud over which the adapter is adapted to he temporarily positioned, and a coaxially positioned supporting member provided with diversely positioned platforms of ascertained proportional height relatively to thelength of the adapter and of the bearing shells respectively, whereon the shells and their temporary enclosing ring may be respectively rest ed, thereby locating both of'the' latter in the exact position desired relatively to the lengthwise extent of the adapter. 6. Means for accurately locating a bearing shell and its temporary enclosing ring in desired position relatively to the ascertained length of a supporting dummy, comprising a central stud over which the dummy is adapted to be positioned, and a plurality of supporting platforms coaxially positioned therea'bout, whereon the shells and their temporary encircling ring are adapted to-be" rested preparatory to their clamping assema blage, the height of said platforms relatively to one another and to the length of the dummy being such as to effect the accurate ositioning ot' the shell and its encircling ring midway between the ends of the dummy.

In testimony whereof, I sign this specificatiOIl. i "f LOWELL o; BLOMSTROM.
